I have ordered this 2 Din 7" touchscreen and case, and am expecting it to be delivered today.

I have also ordered the optional side button kit for it, but it will not be here until the end of the month. Also, I have to come up with a workable UPS solution for my setup, so that when the car it powered off, the Pi will safely shut down.. and when the car is turned on, the Pi will boot up.

I will be running the Raspbian OS with Kodi loaded on startup.
